Scorpion4ik [409]

Answer:

191 people do not have a briefcase

Step-by-step explanation:

Proportion states that the two ratios or fraction are equal

As per the given condition:

On the subway 8 out of 11 people are carrying a briefcase.

⇒Total number of people = 11

and number of people carrying a briefcase = 8

Remaining number of people that do not carrying a briefcase = 11-8 = 3

Now,

Based on this information, if there are 700 people on the subway

Let x be the number of people do not have a briefcase

By definition of proportion :

$\frac{3}{11} = \frac{x}{700}$

Multiply 700 both sides, we have

$\frac{3}{11} \times 700 = x$

Simplify:

x = 190.90≈ 191

Therefore, 191 people do not have a briefcase

Question Find the surface area of the prism. m2

Art [367]

Answer:

324 square meters

Step-by-step explanation:

Hey there!

The surface area of a shape is the area of all the surfaces added up

The side surface area is 48 since 16 x 3 is 48. Since there are two side areas, we need to multiply 48 x 2 is 96

Now we need to do this for the other sides

the bottom and top areas are 96 square meters each so we multiply 96 by 2 which is 192

The front and back faces have an area of 18 square meters so we multiply 18 by 2 since there are two faces which are 36

Now we add all the values: 96+192+36 which is 324

So the surface area of the prism is 324 square meters

How do I factor trinomials of a form ax^2+bx+c when a=1 In one paragraph

vitfil [10]

Answer:

Trinomials in the form $x^2+bx+c$ can often be factored as the product of two binomials.

Step-by-step explanation:

As we know that a polynomial with three terms is said to be a trinomial.

Considering the trinomial of a form

$ax^2+bx+c$

a = 1

$x^2+bx+c$

Trinomials in the form $x^2+bx+c$ can often be factored as the product of two binomials.

For example,

$x^2+7x+10$

$=\left(x^2+2x\right)+\left(5x+10\right)$

$=x\left(x+2\right)+5\left(x+2\right)$

$\mathrm{Factor\:out\:common\:term\:}x+2$

$=\left(x+2\right)\left(x+5\right)$

Therefore, Trinomials in the form $x^2+bx+c$ can often be factored as the product of two binomials.
